There were 20 closed and 4 open Gustilo type II or IIIA fractures secondary to motor vehicle accidents (n=21) or falls (n=3). Patients had undergone one to 3 operations. The mean time from injury to the present revision surgery was 1.3 years. No patient had a flexion contracture. The locked plate was removed and replaced with a retrograde dynamic locked nail (with or without buttress plate augmentation) followed by bone grafting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>17 men and 4 women were followed up for a mean of 3.4 years. The rest were lost to follow-up. The 21 patients achieved bone union after a mean of 4.3 months. The mean maximal knee flexion improved from 97.1\u00b0 to 107.6\u00b0 (p=0.03). Knee function was excellent in one, good in 15, and fair in 5 knees. The fair outcome was due to extension contracture, varus knee deformity, or knee pain. There were 3 malunions with varus deformity of 7\u00b0, 8\u00b0, and 9\u00b0 each. No patient had deep infection causing a nonunion. All 21 patients could walk without aids.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion.<\/jats:title>\n
